Hi folks, I'm Gordon, I finally managed to register with the forum, and here I am. I've got a 1998 Range Rover P38 with a 4.0 GEMS engine fitted with an R90E vapouriser and OMVL Millenium controller.
When I bought the old tank the engine was rattling so I swapped in a lower mileage one with fewer deathly noises and less exhaust gas bubbling out of the header tank - I suspect it had been run low on coolant because the usual heater O-rings were crumbly. They're not as horrible a job to do as people make them out to be. Although it ran on gas when I got it, it wasn't very good. It cut out at junctions all the time and ran like a bucket when it was cold. That said, it ran like a bucket when it was warm too, and wasn't much better on petrol. New lambda sensors improved matters, as did getting hold of a Millenium programming cable and setting the ECU up properly - or, at least as well as I could.
I cleaned out the bowl in the front end shutoff valve. There's a stainless steel screen in there, but no cartridge filter - I'm not sure if this is correct? I also rebuilt the vapouriser with new rubber bits, which made a drastic improvement overall. At some point in its history the cats have been removed, but it still passed an MOT with an understanding inspector and careful fettling with the gas tester on.
It's fitted with two tanks - a massive 95l tank slung across the boot taking up loads of space, and one that I can't see a capacity marked on in the spare wheel well but I reckon it's about 85l given the size. The spare wheel well one has its solenoid disconnected. I haven't tried connecting it to see what'll happen. There's a rather grotty T-piece under the boot floor where the two pipes join, but I'm not sure what happens with the filler. They're both single-hole tanks. The 95l one seems to go from empty to full with only about 45l of gas! That's filling from <cough splutter switch to petrol> to the filler bumping, surely not quite right?
I'd quite like to find a reputable LPG fitter in or around Glasgow that I can get some advice on what to do with these tanks - I want to remove the 95l altogether and if I can get 60-odd litres into the 80l tank I'll be happy enough with that. Oh, and it's got an old-style screw-in filler with an adaptor, which I'd like to change for a proper bayonet one.
So, if you see R454EWW rumbling about, give me a wave
